The influence of spheroniser plate surface protuberance geometry on pellets produced from spheronisation of paste extrudates was investigated using a model paste material (45 wt% microcrystalline cellulose/water). Four cross-hatched pattern plates of different dimensions and/or shape of the surface protuberances were studied in terms of their effect on pellet water content, spheronisation yield, pellet size and shape distributions, and surface morphology. In addition, the effect of the relative size of extrudates to protuberances was investigated by comparing pellets generated from 1 and 2 mm diameter extrudates. In this study, all the plates have the same groove line arrangement but differ in surface protuberance dimensions and/or shape, and so the focus differs from that of Michie et al. (2012) who investigated plates of different groove line arrangement.
